Hello I am having a bit of trouble with my memory card. I had to reset my phone today after deleting an application, as soon as the phone rebooted it stopped reading my media card. I have tried to reset by pulling the battery, and I have tried to play around with the card itself. Any help us greatly appreciated. Thank you

Do you recall seeing a screen on the Pearl asking "Do you want to turn on Mass Storage Mode? You might not be able to access some media files in this mode. (Yes / No) and a checkbox which toggles "Don't ask again"."

I get worried about this sometimes -simply because if I selected No and that box was checked -how would I re-initialize the Mass Storage Mode?

Not sure if this would be related -but possibly.
Do you have multiple machines or a way to check the USB?
